@gian Thank you very much for your explanations, I’ll take a look with my partner because the problem still exists.
It’s not exactly common that you have to manually set a WiFi channel on the router for smartphones/tablets, but in this case it’s worth a try since the problem still exists. The error is probably to be found with Centro Business, since you wrote yourself that your S23 Ultra doesn’t cause any problems in other networks. I am also not aware that the S23 series has or had any general problems with the WiFi.
